methinks these themes have been re-learnt more recently:
-The ferocity of the fight – killing is the only thing that counts.

-Administrative problems, particularly the provision of water and the vulnerability of lines of communication, often determine tactics.

-Much of the terrain dictates that infantrymen do the fighting – armour, field artillery and aircraft may be useful but their presence involves costly technical support.

-Tribal custom and belief can win or lose the day.

-The local enemy leader does not burden his mind with complications such as taking prisoners or evacuating casualties.

-Africa always wins – the invaders or colonizers in the end acquiesce.
